International Gold Markings and Symbols
Gold, a precious metal with timeless beauty and allure, has been used for centuries in jewelry, ornaments, and currency. To ensure its authenticity and purity, international standards have been established for gold markings and symbols. These markings provide valuable information to buyers, allowing them to make informed decisions about the quality and value of their gold purchases.
Gold Karatage Markings
The karatage of gold indicates its purity, expressed as a fraction of 24 parts. Pure gold, known as 24-karat gold, is 100% pure. However, pure gold is too soft for practical use in jewelry, so it is often alloyed with other metals to increase its strength and durability.
Common gold karatage markings include:
* 24K: Pure gold (100% pure)
* 18K: 18 parts gold, 6 parts other metals (75% pure)
* 14K: 14 parts gold, 10 parts other metals (58.3% pure)
* 10K: 10 parts gold, 14 parts other metals (41.7% pure)
Gold Fineness Markings
Finity is another way to express gold purity, measured in parts per thousand. The fineness of gold is calculated by multiplying the karatage by 24. For example, 18-karat gold has a fineness of 18 x 24 = 432.
Common gold fineness markings include:
* 999: Pure gold (99.9% pure)
* 750: 18-karat gold (75% pure)
* 583: 14-karat gold (58.3% pure)
* 417: 10-karat gold (41.7% pure)
Other Markings
In addition to karatage and fineness markings, other symbols may be found on gold items:
* Hallmarks: Official stamps applied by government assay offices to certify the purity of gold.
* Maker’s Marks: Symbols or initials that identify the manufacturer or jeweler who created the piece.
* Country of Origin Marks: Symbols or abbreviations that indicate the country where the item was made.
* Purity Marks: Symbols or words that indicate the specific purity of the gold, such as “925” for sterling silver (92.5% pure).
Understanding international gold markings and symbols is essential for informed gold purchases. These markings provide a guarantee of authenticity, purity, and value, ensuring that buyers receive what they pay for.
